I have read a ton and I still don't quite understand something. Every visible beam seems to stop at some point (it appears to stop) and I kinda understand why, but is there a way to make a 532nm beam go farther, or will a 3W laser go farther than a 200mw laser? I want something that is extremely bright and visible at night (for pointing long distances), I would like to have the beam as thick as I can get it, and I'm not sure if a beam expander would do the trick but it sounds like it might help. I don't really care if it burns or not, and I don't care how much it costs either...
All advice welcome and appreciated greatly, thanks.
